The big challenges of America

The intellectual elite of America defends the democracy and freedom (and of course, the economic interests of the United States). This increase of the american armament is incomprehensible. The cold war ended. Mistrust? There is competition, globalization. If a country loses market your economic power decreases. China... Russia... Etc. The big challenges of America are: leave this imperialist mentality of the cold war. Observe the inevitable growth of other countries.
